Spread means two things in options: the bid-ask spread (the gap between buy and sell prices) and a spread strategy (combining multiple options). Confusing them trips up beginners — here’s both.

The bid-ask spread

The bid-ask spread is the difference between the highest price a buyer will pay (bid) and the lowest a seller will accept (ask). It’s a cost — you buy at the ask, sell at the bid — and a measure of liquidity (tight = liquid). This is the “spread” that matters most for a scalper’s costs.

The spread strategy

A spread strategy combines multiple options into one position — buying one and selling another (a vertical spread, calendar, condor, etc.). Spreads define risk, reduce cost, or target specific outcomes. When traders say “I put on a spread,” they mean this multi-leg structure.

One “spread” is a cost (bid-ask); the other is a strategy (multi-leg position). Same word, unrelated meanings — context tells you which.

The takeaway

Know which “spread” is meant: the bid-ask spread (a trading cost) or a spread strategy (a position). For a single-option scalper like a NoVo user, the bid-ask spread is the one that hits you daily (a real cost).
